Probably the best Basic SEP on the market
T67 Firefly,
I know its expensive to run but worth every extra penny. CAP 10 is asking a bit much to teach ab initio's on a taildragger.
The Firefly gives you the best of both worlds just dont' get the badly underpowered T67 - 160 at least a T67-200 so that it doesn't fall out of aeros as much and you have a trainer that can go from ab initio to IMC and aeros in a oner. If you have a fleet of em then I'm sure that Slingsby will be more than happy to give you a hand.
Robin 2160 is also spinnable. I flew the one at Sherburn a few times, i'm 187 and had no issue at all with the Robin's size. The Bulldog is fantastic as well if you can find one which won't require too much work as I remember they were flown to the limits when I was on my UAS.
